Thin Ag films of (001), (110) and (111) orientations were vacuum deposited on NaCl substrates below room temperature in inert gas atmospheres of about 1Pa. The substrates used were cleaved NaCl crystals and NaCl thin layers deposited onto hot mica and then cooled. Pentagonal particles are frequently observed in those Ag films. Film growth mechanism, especially graphoepitaxy of (110) film, is explained on the basis of a tetrahedral cluster nucleation model, in which promoted migration of Ag adatoms and clusters on the substrate is also considerd.
